Disclosed are a method and device for correcting recovery and analyzing an alarm of a distorted image. The method comprises: receiving an original distorted image collected by a distortion lens, and acquiring original distorted coordinates of each coordinate point in the original distorted image; and acquiring a pre-stored distortion parameter of the distortion lens, determining recovery coordinates of each coordinate point in the original distorted image and acquiring a recovered image. The present invention uses the pre-stored distortion parameter of the distortion lens to conduct corrective recovery processing on the image collected by the distortion lens so as to obtain an undistorted image, so that a displayed image is close to a real scenario, and the recovered image has the characteristic of a large visual angle, thereby preventing the existence of a blind area and a dead angle in common visual angle shooting, which is beneficial for capturing emergencies in a security monitoring environment and improving the accuracy of a security alarm. |
